RECEPTACLE cnos'unn application filed April a1, 1922. Serial no. 638,647.

To all whom it may concern v Be it knownethat I, LESLIE R. N. CAR- vALHo, a citizen of the United States, resid ing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Receptacle- Closures, of which the following is a specification.

This invention relates to a receptacle closure, and is in the nature of an improvement upon the structure shown and described in my pending application, Serial Number 511392 (my file 0-116). k

A particular ob ect of the present improvement is to so construct the closure as to ,render it more adaptable foraccommodating itself to a close fit following the contour of the receptacle and also to accommodate itself to receptacles varying in size within appreciable lunits. I further and more detailed object is to provide a closure having a marginal flange portion adapted'to surround a portion of the receptacle and to rovide said flange with a seam rendering t e flange expansible and capable of expanding to accommodate itself to the contour of the receptacle and to adapt the flange to properly fit receptacles of varying size.

A further object is to provide a closure having a flange portion provided with a seam vertical thereof and said seam constituting an inward projection of the flange adapted to engage the receptacle and to thereby hold adjacent portions of the flange. sprung out of engagement with the recep. tacl e whereby to generate a resilient spring pressure of said seam against the receptacle to prevent likelihood of accidental disengagement of the closure from the receptacle.

A further object is to provide a closure having its flange portion constructed to in-' clude a retaining part. adapted to be torn off therefrom, along a score line, for releasing the closure, and to provide a simple means for protecting the raw edge of the remainder of the flange, said means being incidentally of a character to reinforce the flange.

Other objects and aims of the invention, more or less specific than those just referred to, will be in part obvious, and in part pointed out in the course, of the following escription of the elements, combinations,

arrangements of parts and application of principles constituting the invention, and

the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of this specification, and in which I have shown only a preferred form of embodiment of the invention Figure 1 is a side elevational view of a closure constructed in accordance with this invention, the same being shown partly in vertical section andillustrating the closure in sealing position upon the receptacle.

Figures 2 and 3 are diagrammatic views illustrating the manner in which the closure is adapted to spread when applied to a reccptacle having tapering side walls, Figure 2 showing the condition of the closure just prior to application, and Figure 3 showing the condition after application.

Figure 4 is a detail perspective view illustrating the character of seam employed.-

Figures 5 and 6 are views similar to Figures 2 and 3 butillustrating the manner in which the closure, after removalof the attaching portion, is adapted to spread for providing frictional engagement with the receptacle to retain the closure against accidental dis placement. Figure sectional view for illustrating the manner in which the closure grips the receptacle.

Figure 8 is a view similar to Fi re 7 but illustrating a modified shape of t e closure 7 is a diagrammatic transverse for providing greater frictional engagement between the closure and the receptacle.

Figure 9 is a fragmentary sectional view illustrating the use of an outstanding bead upon the receptacle for carrying the score line which connects the attaching, portion with the remainder of the closure and Figure 10 isa view similar to Figure 9 but illustrating the condition of the closure flange, f

lie

ends are seamed together by a seam 2 extending vertical of the closure. The cover portion is connected in position by means of an annular seam 3.

The seam 3 is preferably, though not necessarily, of a character such that it holds the cover and flange parts rigidly and immovably connected together. At the same time it provides an attractively rounded edge Surface 4 at the upper edge of the closure projecting above the uppermost surface ofthe cover serving at once to frame the cover and to protect against injury any lacquer, paint or other ornamentation carried by the cover.

This seam also serves as an effective reinforcing element for retaining the closure against distortion at all times.

Within the closure and in fa'ctforming a part thereof, resting against the inner surface of=the cover'yis a disk shaped gasket 5 of cork or other suitable gasket material, the same being held in position by frictional engagement with the walls of the flange portion H. In use this gasket is intended to rest upon the upper edge surface of the receptacle.

' The flange portion His made substantially smooth and uninterrupted throughout its entire surface, and it may bear any suitable paint or lacquer, or may be ornamented in any appropriate manner. Its lower annular edge, which normally would extend straight downwardly about the receptacle to a point slightly below the annular shoulder '1 of the receptacle is bent or flanged inward- 13- as at 7 to under-lie said shoulder and to thereby hold the closure against displacement.

The receptacle with which this closure is intended to be used preferably has its portion, as 27, above the shoulder 1. shaped to provide a slight upward taper which is effective in the practical use of the closure in that it enablesthe upper portion of the taper to be sufliciently small so that the closure may be readily introduced thereover and so that the lower portions of the taper will produce a tight fit within the closure when the closure is applied; The frictional grip of the closure against the tapering Sides of the receptacle will be suflicient to hold theclosure against accidental displace- -ment, and this is of course particularly important when there is present only the temporary closure, that is the portion,of the closure remaining after the lower orattach-- ing portion 9 of the closure has been torn off along the score line 8 in ,the manner described in said pending application.

It, is a feature of the present improvement also to make the seam 2 so that it will permit of. expansion and contraction of the flange portion of the closure such expansion may be particularly desirable as a means to enable a given size of closure to be used upon receptacles of varying sizes, also to enable-the flange to accommodate itself to a substantially snug engagement with the tapering sides of the receptacle.

The inter-folding, or inter-locking, type of scam, is clearly indicated in Figures 4 and 7, as well adapted for this purpose since it permits the end portions of the material to move back and forth relative to each other without opening the seam.

The closure may be made of a diameter, relative to the receptacle, such that it maybe readily-introduced over the upper end of the receptacle, as indicated in Figure 2, but such that it must expand, particularly at its lower edge, as it is moved downwardly over the tapering sides of the receptacle. The ex pansion will be resisted by the natural resiliency of the material of which the closure is made so that when the closure has assumed its final sealing position, as in Figure 3, the flange will closely and firmly hug the receptacle. Thereafter the portion 7 of the flange may be, bent into engagement beneath the shoulder 1 for holding the closure in sealing position.

When the attaching portion 9 has been torn oifand the closure thereby released and slid upwardly ofl' of the receptacle the temporary or remaining portion of the closure will return, or contract, to or near its original cylindrical position, as seen in Figure 5. In the subsequent temporary use of the closure it will be caused to spread or expand whenever it is slid'downwardly on to the receptacle, as seen in Figure 6, and in this way a suitably resilient pressure is always present against the receptacle for frictionally retaining the temporary closure against accidental displacement.

The annular seam 3 at the upper edge of the closure serves to hold said upper edge against expansion at all times while leaving the lower edge of the flange free to expand as explained,'so that said seam 3 is thus instrumental in giving to the closure the slight and attractive tapering shape following approximately the taper of the receptacle It will, of course, be understood that in producing the seam 2 the parts thereof are so arranged as to provide suitable 0 en spaces, as indicated at 31, into whichadjacent parts may crowd for facilitating expansion of the closure. Thev movement, however, is almost imperceptibly slight in most instances so that substantially no-bulk is added to the seam.

By reference to the illustration Figure 7 it will be seen that the seam 2 is so constructed as to stand wholly interiorly of the flange where it constitues an inwardly projecting rib which by engaging against the receptacle, and thereby holding out of engagement with the receptacle portions,

as 3%, of the closure, enable said portions "32, by their resiliency, to store an energy when the closure is forced downwardly over the receptacle, which energy will press the seam, and an opposite port-ion as 33 of the closure, resiliently against the receptacle and operate to maintainl the pressure for frictionally holding the closure, particularly the temporary closure, upon the receptacle. incidentally this provision also increases the capability of a given size of closure for properly accommodating itself upon receptacles ofvarying size. 1

The modification Figure 8 illustrates substantially the same subject matter as in Figure 7, but inaddition suggests the presence ,of a plurality of contact points as 34r34. comprising indented portions of the closure flange spaced apart around the closure and thereby providing resilient energy storing portions as 35-35 between them for accomplishing the same results, but in a somewhat increased quantity, as compared with the structure set forth with regardto Figure 7.

in the modification Figures 9 and 10 is illustrated an arrangement of parts by which the score line, as 8, may held away from the side surface of the receptacle. in this instance an annular head which is formed upon the closure, and which is here indicated by the reference character 36, is

made to project outwardly of the closure and the score line 8 is formed directly within this head, preferably in the lower portion of the head but at such locality as to be spaced away from the receptacle. By thus placing the scoreline it follows that when the attaching portion 9 is removed then the raw edge as 37 left upon the temporary closure faces inwardly so that it is'concealed and protected by the outer rounding surface of the bead. Furthermore, since the surface 37 is made to standout o-fcontact with the surface of the receptacle it folldws that when the temporary closure is being put on to and off of the receptacle said edge will not be likely to accumulate scrapings from the side of the receptacle.

The lower edge of the closure will therefore be maintained cleanand attractive.

As many changes could be made in this construction without departing horn the scope of the invention defined in the following claims, it is intended that all matter contained in the above description or shown in the above drawings shall oe-interpreted as illustrative only and not in a limiting sense. 1

Having thus described the invention what I claim as .newand desire to secure by Letters Patent is p 1.
